-When displaying inline images that are larger than the window, Emacs
-does not enable scrolling, which means that you cannot see the whole
-image. To prevent this, the library tries to determine the image size
-before displaying it inline, and if it doesn't fit the window, the
-library will display it externally (e.g., with @samp{ImageMagick} or
-@samp{xv}). Setting this variable to @code{t} disables this check and
-makes the library display all inline images as inline, regardless of
-their size. If you set this variable to @code{resize}, the image will
-be displayed resized to fit in the window, if Emacs has the ability to
-resize images.
+This variable is @code{resize} by default, which means that images
+that are bigger than the Emacs window are resized so that they fit.
+If you set this to @code{nil}, large images are not displayed in
+Emacs, but can instead be displayed externally (e.g., with
+@samp{ImageMagick} or @samp{xv}). Setting this variable to @code{t}
+disables this check and makes the library display all inline images as
+inline, regardless of their size.
